From 1947 through 1956, each BBWAA voter had their own rules for decide who was a rookie. In 1957, the BBWAA first defined the term as someone with fewer than 75 at bats or 45 innings pitched in any Major League season before the current season.[1] This guideline was later changed to 90 at bats, 45 innings pitched, or 45 days on a Major League roster before September 1 of the last year.[1] The current rule is 130 at bats, 50 innings pitched or 45 days on the active roster of a Major League club (except for time in military service or on the disabled list) before September 1 was first used in 1971.[1][7] Since 1980, each voter names three rookies: a first-place choice is given five points, a second-place choice three points, and a third-place choice one point. The award goes to the player who receives the most total points.[1][8]Edinson Volquez received three second-place votes in 2008 even though he was not a rookie under the award's definition.[9][10]
